Title: Broadcasting messages
IPC: G08G1/09
Filed: 1975-09-15
Abstract: 1514941 Radio signalling to road vehicles BRITISH BROADCASTING CORP 15 Sept 1975 [13 Sept 1974] 40084/74 Heading H4L In a method of broadcasting pre-recorded messages, e.g. to the drivers of road vehicles, each message is in speech but preceded by a digitally coded number unique to that message. As described, each receiver is arranged to store the digitally coded number and to compare the next received number with the stored number and only reproduce the message if its number is different from that stored. This arrangement prevents the reproduction of a message more than once and so tends to prevent drivers becoming bored by repeated messages and so switching off their receivers. As described, each message has a digitally coded head code having three parts: (a) type of message, e.g. weather reports or detours; (b) area code pertaining to the district applicable to the message; (c) serial number of message. The receiver may comprise a conventional car radio 20 having tape cassette or cartridge playback 23. A fixed tuned receiver 25, tuned to the special message transmitter, receives all such messages and passes them to a logic system 26 where the message type part of the head code is compared with that set in manually whilst the area code and message serial numbers are stored in a register. The second two sections of the head code of the next message are compared with that stored in the register and only if they are different from that previously stored, is the entertainment tuner 20 muted and the spoken message gated through at 29 to the amplifier 21. The trailing edge of the message is detected by differentiator and causes the contents of a short-term register (Fig. 3, not shown) to be transferred to the longer-term storage register.

Abstract: 1506840 Navigational calculators LICENTIA PATENT-VERWALTUNGS-GmbH 23 Aug 1968 [12 Sept 1967] 40541/68 Heading G4G [Also in Division B7] In an acoustic, proportional navigation, self-guidance system for a torpedo, to prevent, the torpedo aiming directly at the noise source (i.e. the propeller wake) the point of impact with the target ship is advanced from the stern by injecting a disturbance parameter into the torpedo control circuit at a predetermined range from the target. The target distance from the torpedo is measured by observing the change in noise level which occurs during a given track length, and when the predetermined range is reached the disturbance parameter is fed into the control circuit.

A friction welding machine comprises a pair of workpiece gripping means, one means being mounted on a rotatable and axially movable spindle in a headstock and the other means being mounted in a tailstock, each gripping means comprising cams, wedge-shaped prisms in the cams and two wedges to move the prisms radially for initially clamping the workpieces, the prisms being capable of axial movement to finally clamp the workpieces. The headstock 4 and tailstock 2 are mounted on a frame 1, the gripping means in the tailstock 2 having jaws 15a, Fig. 4, with inclined faces co-operating in wedge fashion with inclined faces on cams 27, rollers being provided between the wedge surfaces. The cams are carried in members 26 having inclined faces engaged by inclined faces of wedges 14 on a fork member 25 vertically movable by a piston and cylinder device 22 to move the jaws apart or together for loading and unloading a workpiece, the opening of the jaws being assisted by piston and cylinder devices 29 in the members 26. The headstook 4 supports a spindle 5 carried in bearings 6, 7, the bearing 6 being mounted in a piston 8 and the bearing 7 in the piston cover 9. A piston 10 contained within the piston 8 is provided to move a sleeve 12 along the spindle 5, the sleeve carrying wedges 14 engaging cams 13 which co-operate with inclined surfaces on jaws 15. Rollers 18 are provided between the jaws 15 and cams 13. A clamp mounted on the piston 8 and sensitive to the pressure in the chamber 55 of piston 8 is arranged to grip an endless cord passing round a roller fixed to the headstock and round a roller of an indicating mechanism also fixed to the headstock. The indicating mechanism has a shaft 40, Fig. 7, which carries a scale 42 at one end and the roller at the other. A shutter 45 is carried on the shaft 40 and has an opening 46 to allow light from a bulb 47 to reach a photoelectric cell 48. A worm-wheel 49 movable by a worm 50 engages the shutter 45 so that the initial position of the shutter may-be adjusted. In operation two workpieces are initially clamped in the gripping means and are brought into contact by pressure introduced into the chamber 55, the workpieces meet and pressure is supplied to cause the pressure-sensitive clamp to grip the cord. The jaws 15, 15a move axially within the cams 13, 27 to securely clamp the workpieces. As one workpiece is moved towards the other as the workpieces deform the shutter 45 rotates until the lamp shines on the cell which sends a signal to stop rotation of the spindle and increase the pressure in the chamber 55. After welding, pressure is supplied to retract the piston 8 and release the workpieces.
